如何在TestFX4中做到这一点？

Question

我有一个关于TestFX4的问题。有一个GUI对象，我想在其中将文本设置为TextField（“#SearchField”）。

它在TestFX3中的工作方式如下：

//Load FXML
@Override
protected Parent getRootNode() {
Parent parent = null;

try {
    FXMLLoader loader = new FXMLLoader(); 
    loader.setResources(ResourceBundle.getBundle(ENTITIES_FIELDS_BUNDLE_PATH, Locale.GERMANY));            
    parent = loader.load(this.getClass().getClassLoader().getResource(SHOW_ALL_LAYOUT_PATH).openStream()); 
} catch (IOException ex) {}

return parent;
}

//Set text into Field and check it's there
@Test
public void setBothnamesAndCheckEnabledSearchButton() {
    TextField searchField = find("#searchField");
    searchField.setText("new text");
    verifyThat("#searchField", hasText("new text"));     
}

@Override
public void start(Stage stage) throws Exception {
    try {
        FXMLLoader loader = new FXMLLoader(); 
        loader.setResources(ResourceBundle.getBundle(ENTITIES_FIELDS_BUNDLE_PATH, Locale.GERMANY));            
        AnchorPane pane  = (AnchorPane)loader.load(this.getClass().getClassLoader().getResource(SHOW_ALL_LAYOUT_PATH).openStream()); 

        Scene scene = new Scene(pane);
        stage.setScene(scene);
    } catch (IOException ex) {}
}

@Test
public void setBothnamesAndCheckEnabledSearchButton() {
    clickOn("#searchField").write("new text");
    verifyThat("#searchField", hasText("new text"));         
}

所以我终于找到了一个答案：我在重写的start()方法的末尾调用stage.show()。testFX找不到任何不可见的组件...
